“I was pleased with Pastrnak,” Chiarelli said. “There’s only been a couple players that have shown that at these camps over the years. He’s still got a little bit of a ways to go, but I’m very happy with Pastrnak.”

Pastrnak is a right-shot right wing, which the Bruins currently don’t have on their roster. Asked whether he felt Pastrnak could be a longshot candidate to make the Bruins’ roster, Chiarelli noted that Pastrnak still needs to fill out physically, but didn’t rule it out.

“You never know,” Chiarelli. “I don’t want to place too much of a burden on this kid’s shoulders, but he was good. The hesitation that you have is that he’s 170, 173 pounds. He’s wiry strong, but you never know. Speed, skill, sense is all there. It would be nice, but we’ll see.

“He’s young. To throw someone [in] at that age, at that weight, but there’s been guys that have done it.”

As for Arnesson, Chiarelli clarified that the Swedish defenseman will not turn pro this year. Due to transfer rules, Arnesson would be ineligible to play in the AHL this season if he went pro (only the NHL), so he will play in Sweden next season. It is in his contract that he will attend Bruins’ camp and then go back to his Swedish club.

Under the Swedish transfer agreement, Pastrnak, who is Czech but plays in Sweden, can be signed by July 15 in order to attend camp without the Bruins having to pay more money to the federation.
